Three new promotional pictures have been released for the upcoming sixth season of The Walking Dead, ahead of the new season trailer that will be unveiled at the San Diego Comic-Con on July 10th.

The pictures show Norman Reedus‘ Daryl looking slightly on edge, walking but yet to draw his crossbow. The pictures of Steven Yeun’s Glenn and Lauren Cohan’s Maggie however look more worrying with both of them having their weapons drawn and ready to shoot in what appears to be inside the walls of Alexandria, the new home the group settled in season 5.

The Walking Dead season six begins this autumn on AMC in the US and FOX in the UK.

Check out the pictures below:
